Hydroquinone and IPL Hair Removal - Compatible Simultaneously?

I'm having IPL hair removal in face (1º treatment done), but I have a little brown spots that i want to treat so i bought CLASIFEL HQ 4%. Is it contraindicated with the IPL treatment? I'm skin type 4, and i never take sun. my hyperpigmentation has nothing to do with the hair removal treatment, and is not so intense. So i think that maybe in 2 weeks i can eliminate them, but im concerning about light sensitivity to Intense pulsed light. :(
